FIG-l ATTORNEY United States Patent 3,056,206 MULTI-USE BOW SIGHT ArchieC. Moore, 4 Hoffman Road, High Bridge, NJ. Filed Mar. 19, 1962, Ser. No.180,671 4 Claims. (Cl. 33-46) This invention deals with a sight,mountable on an archery bow, :to permit more definite and accurateaiming of an arrow at the intended target. More specifically, it relatesto an aiming device attachable to the top limb sighting area of a bow,and capable of vertical adjustment for distance, of horizontaladjustment for vertical alignment of the arrow to be shot at itsintended mark, and of combined use of both target and field anchors,using the same yardage calibrations on the sight frame.

With the present bow sights in use today, there is little or no meansprovided for accurately correcting the vertical adjustment, whennecessary. One purpose of the sight of the present invention is toprovide a means, once a sight has been calibrated for distance, wherebyboth target and field anchors may be used. A further object is to permitmore accurate correction of the vertical adjustment for distance, whennecessary. Need for such an adjustment often arises when bow strings arereplaced, or when the weather is muggy, or when arrows of variousweights are used. Other reasons for such adjustment include slightshifting of anchor hand position, different sizes and shapes of feathervanes on arrows, different vane materials, speeding up or slowing downthe flight of an arrow, or any other condition which will bring about achange in the angle of the trajectory of the arrow being shot, ascompared to the original distance calibration on the bow frame.

These purposes are achieved by providing, in the present invention, acalibrated locking adjustable vertical slide plate through which thesight bar is mounted. To obtain corrective distance adjustment,depending upon the results desired, the calibration marks are choseneither above or below the mark originally used in conjunction with thedistance calibrations on the sight frame.

If both field and target anchors are desired to be used, this is readilyaccomplished with the instant sight by first calibrating the bow sightto the bow, using the target anchor, and choosing one of the calibrationmarks on the bottom end of an adjustable vertical slide plate, inconjunction with the distance calibrations on the sight frame. Then, ifuse of a higher field anchor is desired, the differential distancebetween the two anchors is obtained by shooting the bow at a targetwhile using the relating distance calibration on the sight frame, butemploying the calibrated marks on the top end of the vertical slideplate until the correct mark to be used is determined. The differentialdistance then is established and this top end mark is used thereafter inrelation to the distance calibrations on the sight frame. If thedifferential distance needed is greater than the length of the verticalslide plate, then a differential slide bar is used in relation with thedistance calibrations on the sight frame.

A further object is to provide adjustable mounting legs on the sightwhich will adapt the sight for mounting on different bow shapes, thusmaking unnecessary the bendi ing of sight legs, as has been customarilydone.

The invention will be more readily understood by reference to theaccompanying drawing, in which a preferred embodiment is described, andin which FIGURE 1 depicts a rear elevational view of a sight of thepresent invention, while FIGURE 2 presents a side elevation thereof. Aview of the other side of the sight is illustrated in FIGURE 3. Similarnumerals refer to similar parts in the various figures.

Referring again to the drawing, numerals and 11 3,056,205 Patented Oct.2, 1962 represent vertical parallel spaced rods between which (in thespace 12) ride the sights 13 and 14, slide 15 and differential slide bar16. Rod 11 is longer than rod 10,

thereby permitting an upwardly-directed and forked upper 5 end 17 to beattached by screw 18 on top of rod 10 and by screw 19 on top of rod 11.A curved and elongated slot 20 is cut into end forks 17 to enable radialmovement of end 17 (with screw 18 as a pivot), so as to enable a securefit of plate 21 against a bow, to which it is taped. The front face 33of plate 21 preferably is lined with a thin sheet of cushioningmaterial, such as leather. Forked lower end 22 also is mounted similarlyto end 17, with the exception that it is downwardly-directed, so thatscrew 23 which attaches this end to rod 10, serves as a pivot, and screw24 (attaching end 22 to rod 11) rides in arcuate slot 25, therebyenabling the rotation of end 22 to accommodate the bow and enablingfitting of leathersurfaced plate 26 fiat :thereagainst, the plate beingfastened thereto by a screw in hole 27.

Slide 15 has guides 28 protruding into space 12 between rods 10 and 11,which position slide 15 vertically as it is moved when lock screw 29 isloosened. Attached to slide 15 is sight 13 which is attached to threadedshaft 30. The latter screws into and through plate 15 and nut 31 andthus permits horizontal locking adjustment of sight 13. Scale 32 on therear surface of rod 10 may be marked with target distances, and sight 13may be moved vertically (by loosening screw 29) to the desired markdistance. Other sights, such as sight 14 may be mounted along scale 32for immediate use, when necessary.

Slide 15 is provided with sidewardly-bent lip 34 against which ridesdifferential slide bar 16 in a vertical direction. The bar is retainedresiliently in position by thin flat spring 35 attached to slide 15 byscrews 36. Slide bar 16 is provided with inwardly-hooked end 16' whichmay be used when the field anchor is used when changing from the targetanchor. This bar on adjustable slide 15 gives the additionaldifferential between the two anchors.

From the foregoing it will be observed that the sight of the presentinvention is ideal for conditions when more than one person uses thesame how, such as a family use or a commercial target range. When thesight has been calibrated to a bow, anyone is able to shoot it using thesame calibration marks on the adjustable slide when shooting on thetarget and adjusting and using this mark for adjusting all otherdistances. Similar adjustment can be made for different weights ofarrows used, or for a replacement string in the event the string breaks.
